Interviewing at Leidos
Leidos interviews you through a mix of recruiter screens, initial screening, and multiple technical and panel-style conversations. Across roles, the pattern you should expect is structured evaluation of your background, communication, and problem solving, plus role-relevant technical verification tied to what you say you can do.
The topics that show up most often across the question data are Behavioral Interviewing (Technical Skills), Problem Solving (soft_skill), Communication Skills, Python, and SQL. Technical-writing and systems-administration topics are also present in the extracted topic set, as are Information Security, Data Engineering, and Project Management, so the loop you face is likely to map to the technical scope of the role you applied for.
Based on the reported process steps, you may see a panel interview that includes Q and A and technical problem solving, and you may also see a technical screen or technical interviews that focus on your engineering or data fundamentals. Candidate reports also show common real-world themes: interviews often probe for clarity on what you actually did, some loops include a coding challenge, and some decisions can come quickly, followed by post-interview steps like background and drug testing.
Your technical evaluation often behaves like a “prove it” check on your resume, meaning you should be ready for follow-ups that require you to explain your claimed work clearly and connect it to concrete implementation or problem solving.

- 3Technical screen and/or technical interviews
You may be asked technical questions tied to fundamentals and your resume, including in some cases a technical screen or a deeper technical interview. Candidate reports include examples where technical parts verify what you claimed, and some loops include a coding challenge.
- 4Panel interview
A panel interview can involve multiple representatives and may include Q and A and technical problem solving. Some reports describe a verification style where interviewers follow up based on what you answered, and the panel format can feel intense due to multiple voices.
- 5Hiring manager interview and final decision
You may meet the hiring manager for a deep-dive conversation focused on immediate applicability and fit, sometimes including career goals and a focus on relevant experience. The process concludes with a final decision based on technical skills and team fit.

Do this
- Tie every technical claim in your resume to specifics, then be ready for follow-up questions that verify you can explain exactly what you did and why it matters.
- Practice clear reasoning out loud for problem solving questions, since multiple reports describe evaluation of how you think and collaborate, not just final answers.
- Have strong, structured communication ready for both behavioral and technical questions, using concise narratives that make it easy for interviewers to drill into details.
- If the role is coding-heavy, prepare for a live coding challenge as some reports explicitly describe a moderately hard coding challenge as a turning point.
Avoid this
- Avoid generic answers or vague descriptions of past work, since reports repeatedly describe follow-ups that test whether your answers are specific and verifiable.
- Do not assume the recruiter screen is the only interview, since the process can include panel interviews and multiple technical steps across roles.
- If you struggle to connect your experience to the job scope, expect the loop to tighten into deeper verification, as described in candidate reports.
- Do not ignore post-interview steps, since at least one candidate report describes background check, drug test, and work history verification taking about one to two months.
